Knoxville Ductless Mini-Split Systems

Design & Installation for Versatile Cooling Systems

Over our 39 years at Del-Air Mechanical, we haven’t had any two projects that were exactly the same. We know that using existing building assets to fit your changing business needs can come with challenges. That’s why we recommend solutions that can be tailored to your existing structure.

If you are considering a heating or cooling retrofit for your commercial building, Del-Air Mechanical offers ductless mini-split systems. A highly versatile and efficient cooling system, a ductless mini-split system offers several benefits from space flexibility to lower cooling costs.

Ductless Mini-Split Advantages

For businesses that have rooms or zones with different temperature needs, we recommend using a ductless mini-split cooling system. More efficient than a window air conditioner and less invasive than installing new ductwork, mini-splits incorporate a small, wall-mounted or ceiling-recessed indoor unit connected to an outdoor compressor/condenser unit. Depending on the model and your building’s needs, one outdoor unit can control the temperature for several separate indoor zones.

A ductless mini-split system may be right for:

  • Buildings with separate office and warehouse spaces
  • Older buildings without existing ductwork
  • Building additions
  • Any setting where a separate temperature control system is required

With a ductless mini-split, air doesn’t have to travel from a heater or handling unit in another part of the building. This means less radiant energy is lost, making the mini-split an energy-efficient solution. Some models also feature built-in dehumidifiers.

Our Ductless Installation Process

Indoor and outdoor units are connected via a conduit that contains the power supply and condensation drain line. Installing the conduit typically involves drilling a three-inch hole through the wall, which is easy to insulate and weatherproof.

Recessed ceiling units take up no room space at all. Horizontal wall mounted units protrude slightly but are low-profile enough to make little to no impact on the room.
